route.conf
—
static routes config file
The route.conf
file is read by the
staticroute rc.d script during system start-up and
shutdown, and is intended for adding and removing static routes.
Lines starting with a hash (‘#’) are comments and
ignored. Lines starting with a plus sign (‘+’) are run during
start-up, while lines starting with a minus sign (‘-’) are run
during system shutdown. If a line starts with a ‘!’, the rest
of the line will get evaluated as a shell script fragment. All other lines
are passed to route(8). During
start-up, they are passed behind a “route add
-
” command and during shutdown behind a
“route delete -
” command.
route.conf
file resides in
/etc.route.conf
.In this example, the interface for the desired routing changes is set, the IP address on that interface is determined, and a route is added during startup, or deleted during system shutdown.
# Set interface and determine current IP address for added route. !ifname=bnx0 !ipaddr=$(/sbin/ifconfig ${ifname} | awk '$1 == "inet" {print $2}') net 10.10.1 -interface ${ipaddr}
In this example, IP forwarding is turned on during start-up, and a static route added for 192.168.2.0. During system shutdown, the route is removed and IP forwarding turned off.
# Turn on/off IP forwarding. +sysctl -w net.inet.ip.forwarding=1 -sysctl -w net.inet.ip.forwarding=0 net 192.168.2.0 -netmask 255.255.255.0 192.168.150.2
